What is exploratory analysis, how it is structured and how to apply it in Python with the help of Pandas and other data analysis and visualization librariesPhoto by Holly Mandarich on UnsplashExploratory data analysis (EDA) is an especially important activity in the routine of a data analyst or scientist.It enables an in depth understanding of the dataset, define or discard hypotheses and create predictive models on a solid basis.It uses data manipulation techniques and several statistical tools to describe and understand…

Learn how to create an LSTM-based neural network to predict an univariate time seriesPhoto by Agê Barros on UnsplashIn this article you will learn how to make a prediction from a time series with Tensorflow and Keras in Python.We will use a sequential neural network created in Tensorflow based on bidirectional LSTM layers to capture the patterns in the univariate sequences that we will input to the model.In particular we will see howgenerate synthetic data to simulate a time series with different characteristicsprocess…
